NCLEX RN Exam Review Answers
1. A client diagnosed with schizophrenia is slow to respond and appears to be listening to unseen others. Which medication should a nurse expect a physician to order to address this type of symptom?
- A. Haloperidol (Haldol) to address the negative symptom
- B. Clonazepam (Klonopin) to address the positive symptom
- C. Risperidone (Risperdal) to address the positive symptom
- D. Clozapine (Clozaril) to address the negative symptom
Correct answer: C
Rationale: The correct medication to address the symptom described, where the client is slow to respond and appears to be listening to unseen others, is Risperidone (Risperdal). Risperidone is an atypical antipsychotic that is commonly used to manage positive symptoms of schizophrenia. Positive symptoms can include hallucinations, delusions, and disorganized thinking. Haloperidol (Haldol) and Clozapine (Clozaril) are typically used for addressing negative symptoms, such as lack of motivation or social withdrawal. Clonazepam (Klonopin) is a benzodiazepine primarily used for anxiety disorders and seizures, not for addressing symptoms of schizophrenia.
2. Which of the following situations might warrant a laboratory magnesium level?
- A. Hyperthyroidism
- B. Arthritis
- C. Ulcerative colitis
- D. Depression
Correct answer: C
Rationale: Ulcerative colitis can lead to symptoms such as abdominal pain, fever, diarrhea, and weight loss. This condition may impact the absorption of certain nutrients, including magnesium. Therefore, patients with chronic gastrointestinal conditions like ulcerative colitis should be screened for electrolyte imbalances related to impaired digestion. Hyperthyroidism, arthritis, and depression do not typically directly affect magnesium levels in the same way as gastrointestinal conditions like ulcerative colitis.
3. A client has entered disseminated intravascular coagulation (DIC) after becoming extremely ill after surgery. Which of the following laboratory findings would the nurse expect to see with this client?
- A. Elevated fibrinogen level
- B. Prolonged PT
- C. Elevated platelet count
- D. Depressed d-dimer level
Correct answer: B
Rationale: In disseminated intravascular coagulation (DIC), a client experiences widespread clotting throughout the body, leading to the depletion of clotting factors and platelets. A prolonged prothrombin time (PT) is a common finding in DIC. The PT measures the extrinsic pathway of the clotting cascade and reflects how quickly blood can clot. In DIC, the consumption of clotting factors results in a prolonged PT, indicating impaired clotting ability. Elevated fibrinogen levels (Choice A) are typically seen in the early stages of DIC due to the body's attempt to compensate for clot breakdown. Elevated platelet count (Choice C) is not a typical finding in DIC as platelets are consumed during the widespread clotting. A depressed d-dimer level (Choice D) is also not expected in DIC as d-dimer levels are elevated due to the breakdown of fibrin clots. Therefore, the correct answer is a prolonged PT.
4. Select the age group that is coupled with an infectious disease that is most common in this age group.
- A. Infants: High bilirubin
- B. Pre-School and School Age Children: Shingles
- C. Young Adults and Teenagers: Sexually transmitted diseases
- D. The Elderly: Malaria
Correct answer: C
Rationale: Young adults and teenagers are at the highest risk for sexually transmitted diseases due to their sexual activity. High bilirubin is a laboratory finding related to jaundice and not an infectious disease. Shingles is more common in the elderly population, not in pre-school and school-age children. Malaria is not most common in the elderly; it is prevalent in regions with specific mosquito vectors. Therefore, the correct answer is that young adults and teenagers are most commonly associated with sexually transmitted diseases.
5. Which of the following interventions is necessary before insertion of an arterial line into the radial artery?
- A. Ensure that the client does not need surgery
- B. Assess the client's grip strength
- C. Perform an Allen test
- D. Check a serum potassium level
Correct answer: C
Rationale: Before inserting an arterial line into the radial artery, it is crucial to perform an Allen test. The Allen test assesses the collateral circulation to the hand by compressing both the radial and ulnar arteries. By occluding the radial artery and releasing the ulnar artery, the nurse can check if the ulnar artery can adequately supply blood to the hand if the radial artery is cannulated. This step ensures that there is adequate circulation to the hand post-insertion of the arterial line. Choice A, ensuring that the client does not need surgery, is not directly related to the insertion of an arterial line and is not a necessary step before the procedure. Choice B, assessing grip strength, is not specific to the vascular status of the hand and does not provide information about the adequacy of collateral circulation. Choice D, checking a serum potassium level, is unrelated to the assessment of radial artery patency and collateral circulation, which are the primary concerns before arterial line insertion.
